I ALBERT H. DRAUGHON, JR., OF FORT MYERS, FLORIDA MEANS FOR FASTENING ROLL ROOFING T ROOFS Application filed April 23,

This invention relates to means for fastening roll roofing to roofs and firmly holding the same in position while preventing the roof from leaking through the nail holes neces sarily made in the roll roofing material.

An object of the invention is to provide a metallic strip for holding the rolls. the strip being nailed to a root frame through an overlapped layer of roll rooting and provided with prongs adapted to extend through an upper, overlapping layer of roll roofing some distance from the lower edge of the upper layer, the prongs being preferably triangular in shape and ix'ltegral with the strip and 1 extended at intervals along the edges of the strip the entire length thereof.

By locating the prongs on opposite edges of the strip in staggered relation relatively to each other and to the holes in the strip through which fiat headed nails may be driven, the water is kept from running through the holes made by the prongs through the uppermost layer downwardly and through the nail holes in the lowermost layer since there is no hole in the upper layer over the nail hole.

With these and other objects in view which will be developed as the description proceeds I will now describe my invention in connee- 39 tion with the accompanying drawing in which:

Figure 1 is a top plan view of my improved strip with .nails in the nail holes, Figure 2 is a side view of the same, Figure 3 is a sectional view showing the overlapping layers of roll roofing with my 'inyiention in position to be applied thereto an I Figure 4 is a sectional view corresponding to Figure 3 showing the complete roofing and final position of my attaching strip and prongs.

Referring to Figure 1 the numeral 2 designates a metallic strip preferably rolled and provided with holes 3 adapted to receive nails 4. These nails are preferably provided with extended flat heads 5 and may be placed at convenient distances apart throughout the entire length of the strip.

The strlp has sharpened prongs 7 prefer- 1929. Serial No. 357,476.

ably triangular in shape extending from either edge of the stri stances apart, the prongs on the opposite sides of the strip being preferably in staggered relation with respect to each other and with respect to the nail holes in the strip.

'My invention is applied as best illustrated in Figures 3 and 4, that is to say, assuming the strip B to be the lowest roll strip at the lower edge of the roof, my strip 2 is ap plied along the upper portion of the lowest layer of roll roofing and the nails 4 driven through the strip and the first or lowermost roll of roofing B on the roof, the nails extending into the roofing frame.

In practice the metallic strip is cut in about three feet lengths and inserted in the center of the roofing rolls when packed.

After the roofing roll is unrolled and placed in position on the roof the metal strips are nailed along the upper portion of the lower layer of roll roofing the prongs being bent upwardly as shown in Figures 2 and 3 and the nails driven through the metal strip and the lower layer ofroll rooting into the roof frame. Then a second layer of roofing A may be laid to overlap the first layer B and the sharpened prongs pushed through the layer Aythe lower prongs being some distance above the lower edge of the second layer. The prongs 7 can then be bent alternately downwardly and upwardly along the entire upper and lower edges of the strip 2 or if desired the lower prong may also be; bent downwardly so as to clamp the second layer between the outer end of the prongs 7 and the strip 2.

In devices .for fastening roofing as heretofore constructed the prongs of single nails extend below the lower edge of the second layer of roofing. This is objectionable for several I reasons since the lower edges of-the roofing layers being entirely above the lower prongs are liable to work loose. I have found it advantageous that the lower prong should penetrate the second or upper layer a distance above its lower edge and after the prong is clamped against the outer surface of the upper layer it serves to shed the waterand prevent it from running down the surface of p at convenient disthe prong and rotting the roofing but even if a little water pereolates between the prong and the penetrated layer, it will immediately run down to the lower layer and thence run out and will not be held on the roofing.

By having the prongs staggered relatively.

to each other and to one side of the nail holes any water that would seep through the prong holes in the upperl'ayer A will pass to the bottom layer B and run out between the two layers of roll roofing.

The flat headed nails are made to have the lower surface of the heads fit snugly the outer surface of the strip 2 to prevent the seeping of water between said fiat head and the strip. The outer surface'of the fiat head fits snugly the'under surface of the roll roofing and prevents the accumulation of water between them.

Thenails are not placed in the holes in the metal strip until the strip is applied to the roof and the nails are not in the way when the strips are rolled up in tubular form for storage Having now described my invention and its method of use, whatl claim as new is Devices for locking together the upper and lower layers of roofing comprising a metallic strip adapted to extend parallel to the upper edge of a horizontally extending layer of roll roofingsaid metallic strip having rows of integral pron s at its upper and lower edges, said prongs eing staggered relatively to each other, said strip also having at intervals throughoutits length between the rows of prongs nail holes, flat headed nails adapted to pass through the holes and a lower layer of the roofing into the roofing frame, the plane of the surfaces of said prongs being parallel when the prongs are bent upwardly to the edges of the strip, said prongs having sharpened ends adapted to penetrate an upper layer of rolled roofing below its lower edge and bent over to clamp the upper layer of roofing to the strip and to a lower layer of roofing, both rows of prongs penetrating the upper roll of roofing.

In testimony whereof I afiix my signature.
